' 2 Claims.

This invention relates to containers and particularly to cylindrical' containers or boxes made 'of stiff paper, cardboard orlike material. The general object ofthe invention is to provide an improved construction for such boxes and for the covers or lids thereof, as well as a novel method of assembling them.

A further and more specific object of the invention is to'providea novel box construction of the i multiple bottom type, that is, the type of box which has itsbottom, and sometimes its cover,

composed of two or more superposed disks.

Boxes or containers made of cardboard orother such-material have been found generally unsuitable for packing or shipping certain merchandise,

such for example as pretzels and other moisture or grease-containing edibles. In the case of pretzels, for example, the moisture seeps through to the box, particularly to the bottom, and causes.

deterioration thereof, often resulting in failure of the bottom and consequent "loss of the box contents.

Cardboard andlike boxes'have, however, important advantages, Such as-cheapness of cost and lightness of weight. Accordingly numerous efforts have been made to construct such boxes in a manner to reduce'their inherent weakness sufliciently to make them suitable in the instances 3 above specified. ;'I'he present invention accommore clearly appear from the following detailed description and I the accompanying drawings which clearly illustrate the invention.

, In the drawings: v

Fig. 1 is a perspective view of a cylindrical container constructed in accordance with the invention; I

Fig. 2 is a partial sectional view of the container illustrating ,in detail the proposed construction;

.- "Fig. 3 is an exploded perspective view of the essential parts or constituent elements of the container cover or lid; and 7 Figs. ,4 to 8 are perspective views illustrating clearly the method of constructing a box in ac- ,cordance with the invention, the several views depicting clearly the various steps involved.

Referring to'the drawings andparticularly to Fig. 1, there is disclosed a cylindrical container "of the type f to which the present invention is directed, although it will be understood that the 5 end thereof and a removable cover or lid 3 for plishes this end in a novel manner which will closing the upper open end. As is customary, the lid comprises a disk-like portion 4 and a depending cylindrical portion 5 extending from the periphery of the disk portion.

In accordance with the present invention, it is proposed to construct the bottom of the box, and also thecover if desired, by superposing two or more closure members in the form of disks over the open end of the cylindrical body, and attaching'the disks to the body and to each other by applying the disks successively and securing them by means of a flexible adhesive strip, such as paper. Referring to Fig. 2 of the drawings, it will be noted that the bottom 2 of the b x, as illustrated, comprises two similar disks 6, each of which is securely held in place by means of an adhesive strip '7 encircling the circular juncture of the disk and the body, and adherently engaging the peripheral portions of the disk and body. A'trim strip 8 of paper or like material may, if desired, be applied after the bottom has been assembled to enhance the appearance of the box.

It will be noted from Fig. 2 that the cover 3 of the box is similarly formed, the disk-like portion 4 thereof being composed of two superposed disks 9 which are secured to body 5 in the same manner as above described by means of adhesive strips 10. In this case also, the trim strip 11 may be used. While it is preferred to form the cover in this manner, it is to be understood that the invention is directed primarily to the construction of the bottom, since it is desired to overcome the above-mentioned defects of such containers. To more clearly illustrate the essential parts making up the proposed construction, there is shown in Fig. 3 an exploded view of the major elements or parts of the cover, the said elements being the cylindrical body 5 and the superposed disks 9. The bottom construction comprises, of course, the same general elements, the illustration of Fig. 3 serving to disclose the construction generally.

Bearing in mind, the above-described construction, which it is proposed to utilize, reference may now be had to the remaining figures of the drawings for a clear understanding of the proposed method of assembling the parts involved. In the illustration, the method is illustrated as applied to the bottom of the box, but it will be understood that it is equally applicable to the cover. In Fig. 4, the open end cylindrical body 1 of the box and one of the bottom disks 6 are shown in detached relation. As the initial step in the method, disk 6 is placed over the open end of the cylindrical body and the adhesive strip 7 of paper or like material is run about the circular juncture clearly in Fig. 5. This step, as well as those following, lends itself nicely to manual assembly but it may be carried out by machine if desired. In case the method is manually performed, the strip 7 may be drawn off a roll by the operator and it is merely necessary for him to apply the end of the strip to the assembly and then rotate the assembly with one hand, at the same time guiding the strip and pressing it against the disk and body members with his free hand. The assembled elements may be rolled along a table by the operator during this step, or a rotatable head over which the assembly may be placed may be provided.

The strip is completely wound about the bottom, as shown in Fig. 6, and the second of disks 6 is superposed upon the first, as illustrated in Fig. 7. Preferably, the superposed disks adhere to each other and to this end, a suitable adhesive may be provided on the contacting surfaces of either or both of thesemembers. With the second disk in place, the same adhesive strip 7 is con tinued about the peripheral juncture of this disk and the previously assembled members. This step may be readily performed by an operator in the same manner as described above in connection with the application of the first disk. It is desirable that the successive turns of adhesive binder strip constitute one continuous strip, but, in some instances, it may be desirable to sever the strip after each turn to thereby obtain separate binding strips for the superposed disks. The strip is completely wound about the second disk and then severed if no more disks are to be applied. While only two disks are illustrated herein, it will be understood that any number of superposed disks within the limits imposed in practice may be used.

After the bottom has been completely assembled as described, the box is stood on its bottom and pressure applied by pressing downward on the body of the box as well as the innermost disk. This causes the constituent elements of the bottom structure to become compact and to form a relatively solid mass. If desired, the trim strip 8 may now be applied, as illustrated in Fig. 8, in the same manner as were the binder strips.

. of the disk and the cylindrical body, as illustrated I have found that a box constructed in the manner disclosed herein is very strong mechanically and fully meets the requirements of cardboard or like boxes where moisture-containing merchandise, such as pretzels, are to be packed or shipped. The box is particularly eificient in serving its intended purpose when constructed in the specific manner above described, using a continuous binding strip. The method of assembly is economical and requires a minimum of time and efiort on the part of an operator. It will be apparent, of course, that any such changes or modifications as would normally occur to persons skilled in the art are contemplated by the invention and are deemed to be within the scope thereof.

I claim:

1. A box construction comprising an open end hollow body formed of compressible material, a plurality of superposed adhering flat closure members formed of compressible material, each conforming in size and shape with the contour of an open end of said body and disposed thereover, and

a relatively thin flexible binder strip successively encircling the junctures of said body and the individual closure members and adherently engaging the peripheral portions thereof adjacent the junctures, said strip having its edge lapped inwardly upon the flat side of each closure, member, said body and saidmembers being compressed and forming with said strip a solidified mass.

2. A method of assembling a box composed of an open end hollow body formed of compressible material and a plurality of superposed closure members for an end of said body formed of compressible material, which comprises placing one of said members over the end of said body, running a relatively thin flexible adhesive binder strip about the juncture of said body and said one memher with the edge of said strip lapped inwardly upon the flat side of said member, successively and adherently superposing the other of said members on said one member and at the same time individually attaching it to said body in the aforesaid manner of attaching said one member and applying pressure to said body and said members to render them and said strip a solidified mass.
